This is a neat twisted colorful cane marble from an unknown artist. The signature looks like 'Mal 92' - the year, 1992, is clear, so it's definitely a piece of marble history, but I don't know the signature for sure. There's something in the back of my mind telling me I should know who 'Mal' is, but I just can't bring it up. Maybe one of you knows. Anyway, fun marble for a nice price!
